The PI3K-Akt-mTOR signaling pathway has been identified as a key driver of carcinogenesis in several cancer types. As such, a major area of focus in cancer biology is the development of genomic biomarkers that can measure the activity level of the PI3K-Akt-mTOR pathway. In this study, we systematically estimate PI3K-Akt-mTOR pathway activity in breast primary tumor samples using transcriptomic ...


 Purpose: To study the influence of oxymatrine on hypoxic-ischemic brain injury (HIBI) in neonatal rats.
 Methods: Newborn SPF Sprague-Dawley (SD) rats were randomly assigned to 3 groups (10 rats/group): control, HIBI and groups. Neurobehavioral latency each rat was determined after 48 h treatment, pathological changes cerebral cortex evaluated using H&E staining. Hippocampal neu...

ARID1A mutations are observed in various tumors, including ovarian clear cell (OCCC) and endometrioid carcinomas, endometrial, and breast carcinomas. They commonly result in loss of ARID1A-protein expression and frequently co-occur with PI3K/AKT-pathway activating mechanisms. The aim of this study was to test the hypothesis as to whether PI3K/AKT-pathway activation is a critical mechanism in AR...

Diabetic kidney disease (DKD) appears to be closely related to lipid deposition in kidney. The aim of this study was to determine whether high glucose (HG) exacerbated lipid deposition by increasing CD36 expression via AKT-PPARγ signaling pathway. Our results showed that HG activated AKT signaling pathway, followed by an increase in PPARγ that induced CD36 overexpression, ultimately causing lip...

APPL may function as an adapter protein to modulate the phosphatidylinositol 3-kinase (PI3K)/Akt pathway. Although we have previously proven that the PI3K/Akt pathway can suppress androgen receptor (AR) transactivation, the potential linkage from APPL to the AR remains unclear. Here we demonstrated that APPL could suppress AR-mediated transactivation in a dose-dependent manner in LNCaP and PC-3...

Background Puerarin demonstrates a protective effect in many cardiovascular diseases. However, the role of puerarin acute myocardial infarction (AMI)-induced injury and exact molecular mechanisms are not fully understood. Objectives To investigate whether pretreatment improves cardiac function to study mechanism action puerarin. Material methods Thirty rats were grouped into sham group, AMI gro...

Micro-RNAs (miRs) represent an innovative class of genes that act as regulators of gene expression. Recently, the aberrant expression of several miRs has been associated with different types of cancers. In this study, we show that miR301 inhibition influences PI3K-Akt pathway activity. Akt overexpression in MCF7 and MDAMB468 cells caused downregulation of miR301 expression. This effect was conf...

Abstract Background Autophagy is a double-edged sword during the initiation and progression of multiple tumors. The Hippo pathway effector YAP has been proved to be involved in autophagy processes. present study aimed investigate how regulates cell proliferation via lung adenocarcinomas (LUAD). Methods Data LUAD chip GSE43458 was obtained from Gene Expression Omnibus (GEO). RT-qPCR Western blot...

Sorafenib, an antiangiogenic agent, can promote tumor invasion and metastasis. The phosphatidylinositol 3-kinase (PI3K)/Akt/Snail-dependent pathway plays an important role in tumor invasion and metastasis. Yet, little is known concerning the role of the PI3K/Akt/Snail-dependent pathway in sorafenib‑induced invasion and metastasis of hepatic carcinoma (HCC). A human HCC orthotopic xenograft mode...

There is limited data on co-expression of FGFR/FGR amplifications and PI3K/ AKT/mTOR alterations in breast cancer. Tumors from patients with metastatic breast cancer referred to our Phase I Program were analyzed by next generation sequencing (NGS). Genomic libraries were selected for all exons of 236 (or 182) cancer-related genes sequenced to average depth of >500× in a CLIA laboratory (Foundat...
